- Ruiz and Pavón (l.c.) described Sobralia in 1794, without mentioning any specific epithets, though the publication was accompanied by a drawing of a flower (icon. XXVI). Four years later, the same authors (Syst. Veg. Fl. Peruv. Chil. 1: 232–233. 1798) described three species of Sobralia, S. dichotoma Ruiz & Pav., S. biflora, and S. amplexicaulis Ruiz & Pav. (in that order).
